This work reported the successive incorporation of tetrabutylammonium (TBA) into Methylammonium lead Iodide (MAPbI3) perovskite. The thin films were characterized by X-Ray diffraction (XRD), Scanning electron microscopy (SEM), Transmittance electron microscopy (TEM), Atomic force microscopy (AFM), and UV-Visible spectroscopy. It was shown that introducing TBA increases the crystallinity, grain size, surface morphology without pin-hole, and roughness of the MAPbI3 thin films. Moreover, the MA(1-X)TBAX PbI3 thin film shows better stability in a relative humidity of ∼60% after 15 days than the pure MAPbI3 thin film. The obtained results are hoped to be helpful for stability and improvement of the performance of the MAPbI3 thin films by doping TBA cations under ambient conditions.

Introduction

To begin with, nowadays, the Perovskites with formula ABX3 (A = cation (Formamidinium (FA), Methylammonium (MA).), B = metal cation and X is a halogen anion VII halides (Br, Cl, I)), have been demonstrated good absorbers properties for solar cells with higher photovoltaic conversion efficiency (PCE) (Fakharuddin et al., 2019; Weidman et al., 2019). Methylammonium lead triiodide (MAPbI3) solar cells show good optoelectronic properties with a bandgap between 1.4 and 1.5 eV (Wang et al., 2019), a high absorption coefficient around 105cm−1 (Im et al., 2011; De Roo et al., 2016) with amazing PCE = 25% (Xiao et al., 2014; Park, 2015). To manufacture MAPbI3 Solar cells, low-cost and simple techniques have been used to deposit the MAPbI3 film: thermal vapor deposition, two-step vapor-assisted deposition (Chen et al., 2013), two-step solution deposition, and one-step solution deposition (Yantara et al., 2015; Patel et al., 2017). Despite the outstanding PCE reported of MAPbI3 solar cells, the problem of MAPbI3 degradation by the loss of MAI and formation of lead iodide PbI2 under humid conditions and higher temperatures makes use of MAPbI3 difficult (Ko et al., 2015). Concerning to improve the stability of MAPbI3, MAPbI3 was doped by cesium and showed the potential to enhance the stability of MaPbI3 solar cell under UV irradiance conditions (Niu et al., 2016); also on the road for stable MAPbI3, the divalent anion Se2− was incorporated in MAPbI3 structure to increase the atomic interactions between the inorganic and the organic cations (Gong et al., 2018; Li et al., 2018). Considering the ongoing discussion, some researchers have demonstrated that the MAPbBr3 absorber is more stable than MAPbI3; the MAPbBr3 optical absorption is not appropriate for solar cell production (Ahmad et al., 2019).

In this research work, the tetrabutylammonium iodide (TBA) was incorporated into MAPbI3 solution in the form of MA(1-X)TBA(X) PbI3 thin film to study the effect on the structure-property of the MAPbI3 when TBA was incorporated in different percentages. As a result, significant improvement was found in the crystallinity, morphology, optical properties, and stability of the MA(1-X)TBA(X) PbI3 thin film. The obtained results are hoped to help delay the degradation and to enhance the performance of the MAPbI3 thin film by doping TBA cations under ambient conditions.

Materials and Experimental Procedure

Methylammonium iodide (MAI), Lead (II) iodide (PbI2), Chlorobenzene (CBZ), Methylammonium iodide (MAI) and Tetrabutylammonium iodide (TBAI), anhydrous N,N-dimethylformamide (DMF) and dimethyl sulfoxide (DMSO). All compounds were purchased from Sigma-Aldrich, and they were used without any additional purification. The MA1−xTBAxPbI3 solution was prepared in a glovebox by dissolving PbI2, TBAI, and MAI in the solvent of DMF and DMSO; the solution was agitated at 60°C for 3 h.

Characterization Techniques

X-ray diffraction (XRD) was employed to characterize the crystallinity of the films using RIGAKU Ultima IV diffractometer the range of 2θ = 10°–60° using CuKa radiation (λ = 1.5418 Å) at room temperature. The morphology characteristic of thin films was constantly observed by scanning electron microscopy (SEM) model (Quanta 200–FEI) under 1.5 kV accelerated potential in several magnifications (Stewart et al., 2021). In addition, the films were examined by atomic force microscopy (AFM) with 0.5Hz a scan rate. The fringes crystallinity was confirmed by Transmission electron microscopy with 2.5 KV. Also, UV-VIS and PL spectra were characterized using Ocean Optics HR4000 spectrophotometer in the range of 300–850 nm and He-Cd laser source Si-CCD detector Hamamatsu for PL analysis, respectively.

Results and Discussion

In the present work, thin films perovskite MA1−xTBAxPbI3 were successfully deposited on FTO back contact using a simple spin-coating technique. Figure 1 shows the XRD results of the MA1−xTBAxPbI3 where X = (0, 1,2.5, 5, 10). The characteristic peaks located at 14° and 28° match to XRD planes of (110) and (220) respectively in agreement with MAPbI3 structure (Ono et al., 2015; Abdelmageed et al., 2016) without any PbI2 binary phase. Thus, a significant increase was found in the main XRD peaks (110) and (220) intensities and crystallinity by incorporating the TBA amount. Figure 2 represents the zoomed XRD peak in the range of 13°–15°; the small shift was observed towards a lower 2θ degree after the incorporation of TBA compared to the MAPbI3 thin film. Furthermore, the increase in the crystal lattice could be related to a bigger radius TBA (4.70 Å) than a small radius of MA (1.8 Å).

The MAPbI3 thin film with a tetragonal structure where a = b = 8.90 Å, c = 11.12 Å and with insignificant changes due to TBA incorporation where a = b = 8.91 Å, c = 11.11 Å. The crystal parameters details of MA1−xTBAxPbI3 and the grain size were calculated using the Pawley method summarized in Table 1. Moreover, FWHM of peaks (110) and (220) values gradually decrease an agreement of good crystallinity of the films with increasing the amount of TBA from 0 to 5% in Figure 1C. In this respect, the stability of the MAPbI3 main (110) peak remains excellent after incorporating TBA amounts. Especially many studies have been reported that the inorganized Pb atoms affect the surface imperfections of the film, which leads to a decrease in the performance of perovskite devices. In the current work, the TBA arguably shows a significant improvement of MAPbI3 stability that degrades quickly into PbI2 in external conditions (Yu et al., 2018).

Here, the Raman spectroscopy analysis was used to verify the phase identification of pure MAPbI3 and 5% doped TBA Figure 1D. The dominants two vibrational modes were identified for MAPbI3 approximately at 68 cm−1 and 142 cm−1. The intensities of the same vibrational mode increased after incorporating 5% TBA content. The 68 and 142 cm−1 bands matched with the obtained results from XRD that confirmed the incorporation of TBA, which plays a vital role in the formation of crystallinity (Fateev et al., 2018).

Figure 3 illustrates the SEM images of MA1−xTBAxPbI3 where X % (0%, 1%, 2.5%, 5%, 10%). The undoped MAPbI3 shows a small grain size with a smooth surface and good distribution of lead and iodide (Chen et al., 2018). In the same way, the TBA incorporation increase gradually grain size of 210 nm for pure MAPbI3, 290 nm for the doped MAPbI3 with 1.0% TBA, 490 nm for 2.50% TBA as well as with a higher value of 500 nm for 5.0% TBA figure (a–d). This improvement of the grain size of doped MAPbI3 can be due to the crystal growth by decreasing crystal nucleation and lead to good surface coverage and higher crystallinity, as shown by the XRD analysis (Banerjee and Chattopadhyay, 2018; Liu et al., 2020). In this connection, the enhanced crystallinity and grain size could be attributed to fewer defects in the trap state, decreasing the non-radiative recombination in the MAPbI3 surface (Guo et al., 2019).

The specimen preparation technique used for perovskite samples prepared is tripod polishing for perovskite for high-resolution TEM investigation, scratching the perovskite film prepared and putting it in the special grid of aluminum to characterize the samples with TEM analysis, Figure 4 displays TEM analysis of pure MAPbI3 and doped with 5% TBA expose the scattered through lattice fringes spacing of 13.10 Å correspond to [110] crystallographical plan as well as 7.60 Å match with [220] crystallographical respectively. The selected portion of the electron diffraction spectrum shows that pure and 5% TBA doped MAPbI3 films are polycrystalline, where is in good agreement with XRD results (Giesbrecht et al., 2018; Jones et al., 2019).

Figure 5 shows AFM images with 2 and 3 Dimension of undoped and doped MAPbI3, where the measured roughness is varying, that offers a change compared to doped and undoped MAPbI3 where RMS= (147.7, 198, and 168 nm) calculated for the x% TBA where x = (0, 5 and 10) respectively which is measured by the root-mean-square (RMS) (Table 1). Moreover, the RMS value of 10% TBA doped MAPbI3 shows a slight decrease than the incorporation of 5% of TBA, showing the optimum level for large grain size and high roughness in the AFM analysis (Tombe et al., 2018).

Optical and Photoluminescence Study

This experiment performed the optical absorption and photoluminescence measurements for MAPbI3 thin film doped TBA to analyze the optoelectronic properties. Here, Figure 6A illustrates the optical absorption of MAPbI3 pure and doped TBA from 400 to 900 nm wavelength, where the optical bandgap was estimated around 1.55–1.59 eV. Upon monitoring carefully, the variation in the optical bandgap was observed by incorporating the TBA amount (Smith et al., 2019). This significant improvement could be related to pinhole-free TBA doped MAPbI3 films, as shown in SEM analysis (Sun et al., 2017).

Besides, Figure 7 shows the photoluminescence spectrum of undoped MAPbI3 and doped TBA, where the FWHM intensity progressively increases with the increase of TBA content. Doped 5% TBA represents a significantly higher red emission around 55 nm. This emission is three times higher than undoped MAPbI3 thin film. The results could be attributed to reducing trap density states with decreased charge recombination, which improved the thin film’s optoelectronic properties (Brennan et al., 2017; Ngo et al., 2018).

In this context, one of the essential parameters of semiconductor materials is the stokes shift. This shift was observed between the optical absorption edge and PL peak. The comparison of stoke shift values is summarized in Table 2. The stoke shift describes the reduction of lattice parameters in the crystals. The low value of the stoke shift indicates the good photophysical properties of MAPbI3 (Bouich et al., 2021a; Bouich et al., 2021b).

Degradation Study

The degradation of pure MAPbI3 and 5% doped TBA samples were examined under a dark relative 60% humidity environment where samples were stored for 15 days. Consequently, a significant transformation from the black color to the yellow color was observed for the pure MAPbI3 aged sample after 2 weeks which indicated the dissociation of MAPbI3 to PbI2 confirmed by yellow color compared to 5% doped TBA aged sample was less affected (Figure 9).

Figure 8 illustrates the SEM images of the MAPbI3 surface were affected by humidity and the water molecules over the grain boundaries, which led to the degradation of MAPbI3 and the formation of PbI2 and MAI. The TBA cation reduced the grain boundaries to prevent the access of humidity into the film. Furthermore, the 5% TBA doped MAPbI3 has shown a slight crystal structure distortion than the pure MAPbI3 (Huang et al., 2017; Kundu and Timothy, 2020).

Figure 9 displays the XRD patterns and the structural variations through the degradation of the doped and undoped MAPbI3 with the characteristic peak (110) of pure MAPbI3 shows dramatically reduced; however, the 5% TBA doped MAPbI3 thin film observed less affected by the environment as compared to pure MAPbI3.

Furthermore, the environmental effect was studied from the UV-Visible analysis of the 5% TBA doped MAPbI3; Figure 10 shows a slow-down variation in the absorption edge, and the color changed from dark to brown of the sample after 2 weeks in relative humidity (60%). The obtained results confirm that incorporating TBA into the MAPbI3 could decrease the degradation of the methylammonium lead triiodide absorber for photovoltaic application.

Device Spiro/MAPbI3/TiO2/F.T.O Simulation

As we noticed a change in the bandgap of doped with 5% TBA and undoped MAPbI3 has been observed. The effect of thickness and bandgap variation of the absorber layer has a more significant impact on the performance of solar cells. We simulate a proposed solar cell having a model “Gold/SpiroOmTAD/MAPbI3/TiO2/FTO/Glass” to keep this impact on the cell’s performance. Here Gold is used as a front contact, OmTAD as ETL, MAPbI3 as an absorber layer, TiO2 as HTL, F.T.O is working as a back contact, and glass is a substrate (Kundu and Timothy, 2020; Mesbahi et al., 2021; Quan et al., 2019).

Figure 11C show the J-V characteristics curve and clearly show the effect of doped and undoped MAPbI3, Voc was 0.95V, Jsc of 22.4 mA/cm2, FF of 87.1%, and Eta of 18.01% recorded. Here we note that undoped is giving less performance, Voc, Jsc, FF, and Eta were registered as 0.85V, 25.7 mA/cm2, 86.1%, and 20.42%, respectively, which was good as compared to the results of the film growth and crystallinity (Table 3 and Table.1 in Supplementary Materials).

Conclusion

To sum up, from the preceding discussion, it appears that the doped with a small amount of TBA significantly increases the morphology and stability of MAPbI3 thin film for photovoltaic applications. The XRD analysis revealed that the crystallinity of MAPbI3 thin film enhanced with TBA, the TBA affects leading MAPbI3 film with a homogenous, highly rough surface and large grain size, which could cause trap more light in the surface. Similarly, the MA(1-X)TBAXPbI3 thin film shows better stability in a relative humidity of ∼60% after 15 days than pure MAPbI3 thin film. The obtained results are hoped to help delay the degradation and to enhance the performance of the MAPbI3 thin film by doping TBA cations under ambient conditions.
